For those of you that remember just mere months ago the "older" version of tutvid.com was a bit different looking than the new. On the tutorials page for the various programs I make tutorials on I had these sort of flowing glass rollovers. This tutorial is how to make exactly those buttons. Pretty easy, but also pretty tricky, but nothing too, too difficult. We will take a look at tweening in the timeline to create a seamless loop, using the pen tool a little, masking, reversing many frames at at time and more!
